Enough to cobble dogs with

(UK) A large surplus of anything: We've got enough coffee to cobble dogs with. Possible explanations: A cobblestone is a cut stone with a curved surface. These were set together to create road surfaces, in the days before the widespread use of asphalt. The image the phrase contains is that, even after all the roads have been cobbled, there are so many cobblestones left over that things that don’t need cobbling – such as dogs – could still be cobbled. A cobbler repairs shoes, so if you have enough leather to cobble an animal with four feet or that doesn't need shoes, you have a surplus.

Eye- wash

This expression 'eye-wash' is generally used to cover up the anxiety of a person who is seeking a concrete reply or justification for an act or an event that had affected his personal image or caused him a loss. The affected person usually represents his case to the higher-ups and puts forth his demands for redressal. But the authority, in order to avoid embarassment to his organisation or to himself, is not in a position to expose the entire material or evidence which in turn tell upon the credibility of the organisation. In such circumstances, he will usually call for an investigation to satisfy the complainant, but will not be keen in disposing the case. The authority will drag on the issue, (at the same time pretending to be serious) until the seriousness of the issue dies down and no finality is reached. So, ' The investigation on the issue by the authority is an eye-wash'.
